Mechanical Engineering embraces the generation, conversion, transmission, and operation of mechanical and thermal devices and systems. The program is suited for students with a keen interest in science and mathematics. The curriculum in Mechanical Engineering covers the fundamental aspects of the field, stresses on basic principles and educates students in the use of these principles to solve engineering problems.

In the freshman and sophomore years, emphasis is on humanities, mathematics, physics, and computer aided drafting and design with an introduction to design, conventional manufacturing, automation and mechatronics. The junior and senior years are devoted to solid mechanics, applied mechanics, materials, thermodynamics, heat transfer, fluid mechanics, dynamic systems and controls, thermal and mechanical design, manufacturing, finite element analysis, computer aided engineering, and the application of the fundamentals to the solution of the vast variety of problems encountered in mechanical engineering.

The curriculum stresses on Laboratory work and design projects in a teamwork setting as well as on the acquisition of superior computer skills. It is designed to prepare students to face with success the new challenges of the industry and for the benefit of our society. It also includes free and mechanical engineering elective courses in order that the student best fits his/her interest in areas of specialization that includes the classical areas of air conditioning, power plants, turbo machinery, manufacturing, robotics, vibrations and new areas such as aerospace, biomedical, and plastics engineering.

Mechanical Engineering students may decide to earn a concentration in aerospace engineering with emphasis in aeronautics including the areas of aerodynamics, flight dynamics, aircraft design, and airplane propulsion. Finally, a sequence of courses in management has been added to the curriculum to strengthen managerial skills and self-employment.

Graduate Profile

The demand for mechanical engineers is growing at a steady rate. Mechanical engineers apply physical principals such as heat, force, the conservation of mass and energy to design composite products such as vehicles (automobiles, aircraft, others), weapon systems, heating and cooling systems, industrial equipment and machinery, and household appliances. Mechanical engineers need to be well trained in the physical, mechanical, analytical, computational, and experimental practices used in this industry.

The aerospace and manufacturing sectors are considered the most in-demand areas of the industry for mechanical engineers, but emerging technologies such as biotechnology, materials science, and nanotechnology have also created job opportunities. Additional opportunities of employment outside of the discipline also arise for mechanical engineers because the skills and knowledge acquired through earning a degree can be applied to other engineering specialties.

Mechanical engineers research, design, develops, manufacture, and test tools, engines, machines, and other mechanical devices. They work on power-producing machines such as electric generators, internal combustion engines, and steam and gas turbines; and power-using machines such as refrigeration and air conditioning equipment, machine tools, material handling systems, elevators and escalators, industrial production equipment, and robotics used in manufacturing. They also design tools that other engineers use. They usually work in the manufacturing or agricultural production, maintenance, or technical sales. Many acquire the skills and knowledge to become managers or administrators.

A growing demand in the aerospace industry has opened a vast gamma of opportunities for graduate mechanical engineers that posses the technical and administrative skills to embrace state-of-the-art research and innovative technology projects in the most important enterprises located in the U.S., Puerto Rico, and the world. This industry is establishing itself in Puerto Rico and promises to grow at a significant rate in the next five to ten years. Many aerospace engineers have training in mechanical engineering. They design, develop, and test aircraft, spacecraft, and missiles. They supervise and manufacture these products. They develop the technologies for use in aviation, defense systems, and space exploration. Our specialization in aerospace will give students the skills and know-how needed to commence a career in aerospace engineering in Puerto Rico or the mainland.

Aerospace and mechanical engineers are expected to have a fourteen percent growth from 2006 to 2016. In 2006, twenty-two percent of the mechanical engineering specialties were concentrated in the architectural, engineering, and related services industries; fourteen percent were in the transportation equipment manufacturing industry. In that year forty-nine percent of the aerospace engineers were in the aerospace product and parts manufacturing industry. An increase in the number and scope of military aerospace projects and new technologies to be used in commercial aircraft should spur this demand for the present and next decade.

Admission Requirements

Students with Bachelor’s degree in mechanical engineering from an accredited institution can apply directly with the only requirement of a minimum general Grade Point Average (GPA) of 2.80/4.00. Students with a GPA lower than 2.8 can apply and the graduate committee analyzes the case to determine if the student can be admitted.

Students with Bachelor’s degree from other engineering programs can apply for admission. Additional undergraduate pre-requisites may apply after the evaluation of the application by the program coordinator. The number of undergraduate credits must not exceed 12 credit hours, if it exceeds this amount the student must enroll as a special student in the bachelors program to be able to take the necessary pre-requisites. After the completion of these credithours the student may apply to the master’s program.

Degree Offered

Students in the Graduate Program in Mechanical Engineering earn a Master’s in Engineering with Specialization in Aerospace. Students are required to prepare a design project that result in a technical paper.

Curricular Sequence

The structure and sequence of the curriculum include blocks of courses classified as Core, Area of Specialization, Elective and Design Project.
